Run several queries

I have several update queries that I want to run one at a time until: (0 row(s) affected) is in the message box. Once the query runs without any updates, I need the process to move to the next query.  I found some articles that talk about
macros, but could not locate the tools within SMS. I have very little experience with SQL Server Management Studio, so please excuse me if the answer is abundantly simple.

1.  I have multiple queries that identify and correct null values in a given field. When the null value is identified the value in the preceding record which is the last known good value is updated into the field with the null value.
2.  Running said query one time does not ensure that all the null conditions have been properly addressed. The only way to ensure that all the conditions have been addressed is to run the query until the row count equals zero.
3.  The first code that I have listed: WHILE 1 = 1 BEGIN UPDATE [Master Archive] SET [BackPress 1] = [Nulls BackPress 1].Trial FROM [Nulls BackPress 1]INNER
JOIN [Master Archive] ON [Nulls BackPress 1].SiteID = [Master Archive] .SiteID AND [Nulls BackPress 1].NewTime = [Master Archive] .NewTime
WHERE  ([Nulls BackPress 1].[BackPress 1] IS NULL) AND ([Nulls BackPress 1].Trial IS NOT NULL) IF @@ROWCOUNT = 0 BREAK;END Will run the query until row count equals zero, this ensures that all the null conditions have been addressed.
4.  I have over fifty (50) queries that have to be run. The code above will only run a single query. This Forum has shared with me how to run multiple queries in sequence, however the code will only run each query one time, which is not what
I am trying to achieve. I need every query to run until row count equals zero and then proceeds to the next query.
The following code will run many queries in sequence, but only once:
UPDATE [Master Archive] SET [BackPress 1] = [Nulls BackPress 1].Trial FROM [Nulls BackPress 1]INNER JOIN [Master Archive] ON [Nulls BackPress 1].SiteID = [Master Archive] .SiteID AND [Nulls BackPress 1].NewTime = [Master Archive] .NewTime
WHERE  ([Nulls BackPress 1].[BackPress 1] IS NULL) AND ([Nulls BackPress 1].Trial IS NOT NULL) IF @@ROWCOUNT = 0 RINT 'One Done' PDATE [Master Archive] SET [DiffPress 1] = [Nulls DiffPress 1].Trial FROM     [Nulls DiffPress 1]INNER
JOIN [Master Archive] ON [Nulls DiffPress 1].SiteID = [Master Archive] .SiteID AND [Nulls DiffPress 1].NewTime = [Master achive] .NewTime HERE  ([Nulls DiffPress 1].[DiffPress 1] IS NULL) AND ([Nulls DiffPress 1].Trial IS NOT NULL) F @@ROWCOUNT =
0 RINT 'Two Done'; Note: the print statements are there just to validate the running of the queries, they will not be necessary once I have validated the query
There has to be a way to code the first example so that multiple queries can be run from a single query, I just am not experienced enough to figure it out on my own.
5. In summation: each query must run until row count equals zero, then proceed to the next query

  • Several Queries in one Repeating Report

    I have an employee production report. There are several queries that combine to display several different sets of data for only one individual. I want to be able to just run one report and see not just one employee, but every employee under a given manager. Right now the parameter is set to be the individual employee, but managers need to be able to run just on query and see all of their employees' production, so what I need to be able to do is have a report with a manager as the parameter, and display each and every one of his/her employees. With just one query and one set of data, simply grouping by thaT field would suffice, but my report contains about 5 different queries per individual. I've tried using a UNION query, but does Reports Builder not have a way to do this within the application rather than having to do it in the SQL?

    You would use a subreport to do this. You will need to be sure and link the input variables from the main report to the subreport to keep the rowsets in synch.

  • Prevent BeX Analyzer from stealing focus while executing several queries

    Hi all,
    we have a vba program that runs several 3.5 queries in Excel (SAPBEXrefresh)
    Does anyone knows a solution to prevent BeX Analyzer from stealing the focus each time a new query starts or completes.

    I too am trying to find solution to this very same problem.
    I created a Excel VBA program to batch process BEx reports, which works great, but the users are finding that they can't work on anything else while the process runs, as BEx always returns the focus to the Excel window as each BEx report run is completed!
    In our googling, we ran across the following thread, which I've found so far to have the most detailed discussion of this problem:
    http://sap.ittoolbox.com/groups/technical-functional/sap-bw/sapbex-takes-focus-1188178?cv=expanded
    Unfortunately, no final resolution was provided there, and the thread is over 2 years old, and it looks like the poster who was closing in on the solution hasn't logged in to that particular forum in 2 years as well.
    But why don't you take a look at the link anyway, as it may give you some ideas. I will also continue to use that poster's ideas to try to work out a solution, and if I come across one, I will certainly share it with you.

  • Will it be possible to run several jobs in background at the same time?

    Hi!
    The new release looks promising. Look forward to hear more in Birmingham.
    Just now we have a problem. It have to do with functionality In Toad compared to SQL Developer.
    Will it be possible to run several jobs in background at the same time. Toad allows that.
    If yes: How can we make that happen?

    "Jobs" are always background.
    But I take you mean queries. Yes, since v1.5.x you can open an Unshared SQL Worksheet (ctrl-shift-n or the toolbar button).
    Have fun,

    You can run multiple queries exactly the way you posted them but you need to use F5 - the run script toolbar button.

  • How to always hide the SQL statements for users when they run User Queries?

    Hi,
    from the IT dept. position, I don't want users to see and be so curious about the SQL commands.
    How can I always hide the textbox of  Display Query Structure?
    thanks.

    Hi,
    Unfortunately system design has short of this function. If users are allowed to run those queries, you can not hide the query structure.

  • Run several copies of a VI without using application controls

    I want to run several copies of the same VI depending on the parameters the user answer (1 to 4 copies of the same VI). I would like the VIs to run simultaneously because it controls a different equipment. I read the document about multithreading and I found out that this is possible by declaring the VI "reentrant". I tried, but when I do that, the front panel of the copies of the VI doesn't show up! My application will be built as an executable soon, so I can't use the server applications. Does anyone has an idea to solve my problem?

    I think the easiest thing to do is make the reentrant vi a sub-vi... then
    let a Main UI vi have controls and indicators made visible by the "user
    answer" you mentioned. I don't know what you plan on doing in the vi, but
    you should be able to pass initial control parameters into the sub-vi's and
    get display data out by letting the sub-vi's complete or by using a global
    variable.
    just a thought...

  • Running several instances of BPEL PM on the same machine ?

    Hi,
    What is the best setup to run several conccurent instances of BPEL PM on the same machine (Middle Tier install) ? Of course I would like to minimize the number of components I would need to install.
    - Do I need to install several Oracle AS instances (1 Oracle AS = 1 Oracle Home for each BPEL PM instance) ?
    - Do I need several Oracle databases for teh dehydration ? (apparently not : http://clemensblog.blogspot.com/2006/02/using-oracle-xe-for-bpel-dehydration.html)
    Thanks

    Hi unfortunately it is NOT supported to run more then one container with BPEL / and the isntaller will refuse to install inta a midtier that already has BPELPM installed ..
    w/o is more j2ee webcache installs (they are basically just the container, em and webcache) and connect them to the DB (different schemas if needed, for failover against the same)

  • Information on how to run SQL queries on the CUCM itself please

    Good Day All,
    I need to run an sql query on the CUCM to list all of my directory numbers, their partition, and their external mask values.
    I came across this excerpt below earlier so I have a bit of an idea how to do it but iw would be great to see some other examples of sql queries.
    Any assistance is most appreciated.
    Also, is there a document somewhere to tell me how to run these queries?
    Thanks in advance

    Re: Is there a way of pulling a report off CM showing all phones that have diverts on?
    Try if running this SQL query from the CLI helps you, it should list all DN's that have CFA enabled to VM or a DN:
    run sql select dnorpattern,cfadestination,cfavoicemailenabled from CallForwardDynamic c, numplan n where c.fknumplan = n.pkid and (cfadestination != '' or cfavoicemailenabled ='t')

    Hi Amanda
    Basically it's standard SQL, so it wouldn't hurt to google 'informix select statements' and do a little reading to get the basics. There are millions of permutations of queries so it's a matter of understanding the syntax, and then applying that to the database in question. The only difference when running commands from the CLI are that:
    - You prefix the standard informix SQL statement with 'run sql'
    - You don't get any help from CUCM with the syntax, so you might be well advised to use something that understands SQL a little and colorises it as you type, and then paste the resulting commands into the CUCM SSH window. I use a text editor named JEdit, if you create a text file and save it as a file ending in .sql it will highlight your syntax.
    - Other programs are available that do reasonable syntax highlighting (e.q. SquirrelSQL) that are designed for querying the DB directly, but you can't actually query directly against the DB for security reasons. You'd still have to copy/paste the commands.
    Now... to understand the DB you'll need a reference describing all the tables etc. This is here:
    http://www.cisco.com/en/US/products/sw/voicesw/ps556/products_programming_reference_guides_list.html
    Pick your version of CUCM and download the 'Data Definition' document.
    A few notes on the command:
    run sql : is just the CLI command that tells the shell to run the following text as SQL.
    select : the SQL command to retrieve data
    dnorpattern,cfadestination,cfavoicemailenabled : the column names to retrieve
    callforwarddynamic c, numplan n : the names of two tables, and the abbreviations you want to refer to them as
    where c.fknumplan = n.pkid : this tells SQL to return values from the two tables where these fields match up. In the data definition you'll see notes that c.fknumplan (i.e. the fknumplan column in the callforwarddynamic table, as noted by the c. prefix) refers to the PKID column in the numplan field. This is a very standard type of join in the CCM DB.
    and (cfadestination != '' or cfavoicemailenabled ='t') : another clause, basically in this query we want to see only rows where cfadestination isn't blank or cfavoicefmailenabled is set to 't' for true).
    Most tables are linked in one of two ways in this database:
    - a column prefixed 'fk' refers to the pkid field (there is always only one pkid field per table) in the table following the 'fk' prefix. E.g. above fknumplan refers to the numplan table, pkid field. fkdevice would refer to the device table, pkid field.
    - a column prefiex 'tk' refers usually to an enum table which is prefixed with 'type'. This is a table that maps the number value in the 'tk' field to a string. An example would be tkmodel - this represents the phone physical model type (e.g. 7962), and maps to a table called typemodel, and the 'enum' column in that table.

  • Long Running SQL Queries

    We have a customer that runs our Crystal Reports and they have complained that some of the reports cause long running sql queries and they have to kill these queries manually from SQL Management tools. We have changed the code so that we now dispose the report source and viewer objects as we call .dispose() function on them;
    reportSource.dispose();
    viewer.dispose();
    At first this seemed work but customer later complained that the issue still occurs. Can anyone help with why some of these CR queries are still running way after report is generated (with correct set of data), and based on the customer some of them running for more than 2 hours? What else can we do to make sure that all CR related queries cease to exist once report is generated? Appreciate all the help.

    1. Run the report from with Crystal designer. You should see the query being sent to DB server. After the report is viewed and you close it in designer, do you see the DB connection being dropped? If not, this may not be a SDK\ API related issue.
    2. Try using latest set of CRJ Jars [here|http://downloads.businessobjects.com/akdlm/crystalreportsforeclipse/2_0/crjava-runtime_12.2.213.zip] in your application. Also update the crystalreportviewers folder with the new viewer found at this link.
    3. Make sure that you are calling reportClientDocument.close() at the end when user is done viewing the report.
    4. When you say logn running queries are seen in DB, are you referring to a DB connection left open? or is it actually running any query and returning results?

  • Precision Changes when running parallel queries in Oracle?

    I am trying to speed up our SQL queries and database draws by running parallel queries. However, we are noticing a slight difference in one of our queries. We have identified two possible reasons. One of those reasons is parallel queries for some reason have either less or more precision than what we were doing.
    Has this ever been reported before? Is it even possible? Thanks for any help.

    One of those reasons is parallel queries for some reason have either less or more precision than what we were doing.What do you mean? Show us an example of that happening and exactly what you mean.

  • Best Policy to run open queries on LIVE Database

    Hi Experts,
    There are users who has RO access on Live database , they run open queries on Live database. Sometimes we have faced some issues on Live Database due to open queries and we can not restrict them to run as well. So would like to get your suggestion
    to come up with best solutions ? 
    Shivraj Patil.

    What issue do you have? One option is tuning the query, means create proper indexes to speed up the query..
    But  the user may run heavy query even being unaware  that system consumes resources, for example
    --A typical parallel query...
    SELECT 
        p.ProductId, 
        p.ProductNumber,
        p.ReorderPoint,
        th.TransactionId,
        RANK() OVER 
            PARTITION BY
                p.ProductId
            ORDER BY
                th.ActualCost DESC
        ) AS LineTotalRank,
        RANK() OVER
            PARTITION BY
                p.ProductId
            ORDER BY 
                th.Quantity DESC
        ) AS OrderQtyRank
    FROM bigProduct AS p
    INNER JOIN bigTransactionHistory AS th ON
        th.ProductId = p.ProductId
    WHERE
    p.ProductId BETWEEN 1001 AND 5001
    GO

  • Performance question 1 query with several tables, or several queries?

    Say I want to gather data from various tables, for instance.
    1. big query like this....
    Select col1, col2, col3, col4, col5
    from tab1, tab2, tab3, tab4, tab5
    where tab1 = tab2
    and tab2 = tab3
    and tab3 = tab4
    and tab4 = tab5;
    or
    different queries in a cursor (to gather each column i need), like this...
    cursor c_1 Is
    select col1
    from tab1
    where col1 = :param
    cursor c_2 Is
    select col2
    from tab2
    where col2 = :param
    cursor c_3 Is
    select col3
    from tab3
    where col3 = :param
    cursor c_4 Is
    select col4
    from tab4
    where col4 = :param
    Efficiently, what's better, faster and resources saver?
    Gracias a lot.

    Truthfully, the only way you will know or sure is to run both queries and compare timing results and resource demands. The phrase "your mileage may vary" applies here. Anything else anyone tells you is a rule of thumb which is most often going to be correct but may have exceptions to that rule.
